The game board sends commands to the sound board over a 16-bit
unidirectional data bus. The CPU cannot write all sixteen lines
atomically, it write to lines 1-8 as one group and 9-16 as another
group. Not all bit functions are known:
group. However only seven lines are actually connected to the sound
board:

There could well be other connections on the sound board - these are
just what can be deduced by tracing the sound program.
The game board makes the the audio output from the first S2636 PVI
(5E) available on a pin at the sound board interface connector, but
it may or may not be routed anywhere.

Laser Battle/Lazarian notes:
* Manuals clearly indicate the controls to fire in four directions
are four buttons arranged in a diamond, not a four-way joystick
* Cocktail cabinet has an additional "image commutation board"
consuming the screen flip output, presumably flipping the image by
reversing the deflection coil connections
